Q: why do you need to heat steel when hardening, molecules etc etc: Halps is off base a little. The reason heat is involved in hardening of steels depends, a little bit, on how you are doing the hardening. If you are hardening by work hardening, you do not have to heat it at all. If you are barbarizing (case hardening), the temperature is raised to increase the diffusion rate of carbon into the steel, higher C content - higher hardness. If you are Thur hardening, you have to heat the steel to the austenitizing temperature (so the structure transforms to FCC crystals with higher solubility for C) and then quench it (cool it rapidly enough to freeze the C atoms in the martensite crystal structure). If you slow cool, the steel could end up softer than it started. All of these processes involve atomic level things. If you want to understand them on the atomic level, you need to study physical metallurgy of steels. It is a subject onto itself and is really quite fascinating if you are interested.

Q: What are the different coil leveling methods used for steel coils?: There are several coil leveling methods used for steel coils, each with its own benefits and limitations. Here are some of the most common methods: 1. Roller Leveling: In this method, steel coils are passed through a series of rollers that apply pressure to flatten and level the coils. Roller leveling is effective in reducing coil crown or center buckle, and it can also help eliminate coil memory. However, it may not be suitable for coils with severe shape defects or variations. 2. Stretch Leveling: This method involves stretching the steel coils to remove any shape defects. The coils are passed through a series of gripper heads that hold the edges of the coil while it is stretched. Stretch leveling is particularly effective in correcting crossbow and edge wave defects. However, it may cause some elongation and yield loss in the material. 3. Temper Pass: This method involves passing the steel coils through a series of temper mill stands, where they are subjected to tension and compression forces. Temper pass leveling helps improve flatness and remove coil memory. It is commonly used for thinner gauge steel coils but may not be suitable for thicker coils. 4. Corrective Leveling: This method is used for coils with severe shape defects. It involves selectively removing material from specific areas of the coil to correct the shape. Corrective leveling is a labor-intensive process that requires skilled operators, but it can effectively eliminate shape defects and improve flatness. 5. Tension Leveling: In this method, the steel coils are subjected to tension forces while being passed through a series of pinch rolls. Tension leveling helps remove coil memory and improve flatness. It is particularly effective for coils with edge wave defects. However, it may cause some elongation and yield loss in the material. These are just a few of the coil leveling methods used for steel coils. The choice of method depends on the specific requirements of the steel coils and the desired flatness results. It is important to consider factors such as material thickness, shape defects, and production capacity when selecting the appropriate leveling method.

Q: What are the different types of steel coil processing equipment?: There are several different types of steel coil processing equipment, including coil slitting machines, coil cut-to-length machines, coil leveling machines, and coil edge trimming machines. Each of these machines serves a specific purpose in the steel coil processing industry, helping to efficiently and accurately cut, shape, and prepare steel coils for various applications.

Q: What are the typical coil thickness options?: The typical coil thickness options vary depending on the specific application and industry. However, common coil thickness options range from 0.005 inches (0.127 mm) to 0.249 inches (6.32 mm). These options provide a range of flexibility and durability for different purposes, such as in automotive, construction, or electrical industries.

Q: what are the properties that can strengthen the steel to withstand earhquake?: Well, its not necessary how strong steel is but how buildings are designed that withstands earthquakes. Steel as a property has to elastic qualities and when earthquakes are initiated but moving of the plates, the building has to absorbed the effects of the earth movements while remain standing. This does not necessary mean that the building will be usable afterward but it has to remain standing. Now, how does a building remain standing? All building have within its design a VLLRS (vertical lateral load resisting system). This system is basically designed to resist earthquake loads as well as wind loads. In steel buildings, this system is usual made of OMF (Ordinary moment frames) or braced frames. These frames act to absorb the lateral loads and transmit them into the foundation below. If the structure was concrete, there would still be moment frames made of concrete and steel but you know that concrete has a elasticity that is less than steel. ALthough there elasticity is less, they are stiffer and concrete structure tend to resist more lateral load because of it. In concrete, we can create shear walls which are basically walls that are thick and wide to resist lateral load from earthquake and wind. Masonry has even a lesser strength than steel or concrete and wood even less than above. What makes them usful is how they are used to resist earthquake loads or lateral loads from earthquake and wind. So, to answer your question, its not nessary how strong the steel is but how the material is used to resist earthquake is what is important.

Q: How are steel coils used in the production of automobile frames?: Automobile frames rely heavily on steel coils, which are indispensable for their production. These coils, crafted from top-notch steel, undergo a process of uncoiling before being fed into a stamping press, where they assume various forms, constituting parts of the frame. The presence of steel coils is crucial as they furnish the frame with the requisite strength and rigidity, ensuring it can bear the vehicle's weight and maintain structural integrity. Once shaped, the coils are frequently welded together to construct the frame structure. This welding procedure securely binds the individual components, guaranteeing that the frame can endure the forces and strains encountered during the vehicle's operation. Utilizing steel coils in the production of automobile frames also allows for design flexibility, as they can be effortlessly shaped and manipulated to fulfill specific requirements. Moreover, steel coils possess exceptional durability and corrosion resistance, rendering them ideal for automotive applications. Frames fashioned from these coils are not only robust and dependable but also capable of withstanding harsh conditions and road vibrations. This not only enhances the vehicle's safety but also contributes to its longevity and overall performance. Steel coils also find use in other critical vehicle components, including suspension systems, chassis, and body panels. Their versatility, strength, and cost-effectiveness make them a favored choice in the automotive industry. Overall, the incorporation of steel coils in automobile frame production plays a significant role in guaranteeing the safety, durability, and performance of modern vehicles.

Q: I know that steel is generally iron with carbon and probably some other things in it, but I'm doing a research paper on architecture in Tokyo, and touching on the Tokyo Tower.The Tokyo work is larger than the Eiffel Tower by 12 meters, but lighter by 3000 tons. The only reason I can find for the difference in weight is that the Tokyo Tower is made of steel and the Eiffel Tower in made of iron, and since the Tokyo Tower is modeled after the Eiffel, there's really not a substantial difference in the amount of metal used....: For the same volume of part, like a cubic inch, the weight is very close. If you base the comparison on strength, like a bar strong enough to hold XXX pounds, then the forged bar will be lighter, smaller still hold the weight.

Q: How are steel coils used in the manufacturing of garage doors?: Steel coils are used in the manufacturing of garage doors as they provide the necessary strength and durability required for the door panels. These coils are formed into various shapes and sizes to create the panels, which are then coated and insulated to enhance their performance and appearance. The use of steel coils ensures that the garage doors are sturdy, long-lasting, and able to withstand the daily wear and tear associated with regular use.
